Fafnir (ファフナー Fafunaa) is a Guardian in Soulcalibur Legends. It is the first dragon fought in the game, and Siegfried Schtauffen will end up fighting it three times by the end of the game. It attacks using its claws and its fire breath, and unlike other dragons in the game, it will fly around and attack simultaneously. Fafnir can be attacked using Leonardo's dragon-slaying devices.
- In Nordic Mythology, Fafnir is the great dragon slain by Siegfried.
